How do I implement the basic tree-rotation functions in java? Here are the rotation functions that I want to implement: L-rotation, R-rotation, LR-rotations, RR-rotations, LL-rotations and RL-rotations.  Use the given tree nodes as an example: TreeNode tr = new TreeNode();tr.root = new Node('A');tr.root.left = new Node('B');tr.root.right = new Node('Y');tr.root.left.left = new Node('N');tr.root.left.right = new Node('X');

Please fill in the code gaps if possible. This problem has been giving me trouble. Any help is appreciated.  public class Node {       private String element; // we assume elements are character strings         private Node next;  /* Creates a node with the given element and next node. */ public Node(String s, Node n) {  //fill in body  }  /* Returns the element of this node. */ public String getElement() {  //fill in body  }  /* Returns the next node of this node. */ public Node getNext() {  //fill in body  }  // Modifier methods:  /* Sets the element of this node. */ public void setElement(String newElem) {  //fill in body  }  /* Sets the next node of this node. */ public void setNext(Node newNext) {  //fill in body  } }

What is the easiest way to fix a Node Constructor in my Java program? The current problem is it does not accept the Object being passed into it.

Write the java code to get the 10 out of the tree.
